摘　　要：以脂环族环氧树脂为基体,空心玻璃微珠(HGMS)为填充材料,分别采用真空辅助等静压成型工艺和模压成型工艺制备了固体浮力材料,并对其性能进行了研究。结果表明:相较于模压成型工艺,采用真空辅助等静压成型工艺制备的固体浮力材料可以有效降低材料密度,提高最大可使用深度。在不断提高HGMS体积分数以得到更低密度深海固体浮力材料时,真空辅助等静压成型工艺制备的固体浮力材料比模压成型工艺制备的固体浮力材料的最大HGMS体积分数可提高1%,密度降低了4.86%,最大可使用深度提高了50%,可达3000 m。With cycloaliphatic epoxy resin as the matrix,hollow glass microsphere(HGMS)as the filling material,solid buoyancy materials were prepared by vacuum assisted isostatic pressing forming and molding process,and their properties were studied.The results show that compared with the molding process,solid buoyancy materials prepared by vacuum assisted isostatic pressing can effectively reduce the material density and increase the maximum usable depth.When continuously increasing the HGMS volume fraction to obtain lower density deep sea buoyancy materials,the maximum HGMS volume fraction of vacuum assisted isostatic pressing molding materials can be increased by 1%,the density can be reduced by 4.86%,and the maximum usable depth can be increased by 50%,up to 3000 m.
